To verify your approach, you can use the --stdout parameter to check to see what is being output.

Not knowing any better, what is the value in carving up the search space based on human-readable criteria? Why not just use -s/--skip and -l/--limit naturally, and the math like: https://hashcat.n...

Yes, newer Office hashes are pretty slow. You can add -w 4 and -O; that might help.

    Thread: Hybrid Attack
Post: RE: Hybrid Attack

Nevertheless, that's the answer. Because of how hashcat is optimized to run, undersized masks on the left-hand side have more of an impact on speed than undersized masks on the right-hand side.

Post: RE: is hashcat still support VCL?

VCL is no longer supported. Intel GPUs are supported via OpenCL, though there are some known problems with Intel's GPU OpenCL implementation, so YMMV.

Post: RE: Separator Unmatched! Please help!

Does your attack work against the example hash? If so, the problem is probably your hash. Double-check to ensure that the field count is identical.
